> I also want the ability to subscribe to an author or a book series and be notified of new releases.
I also want this and am kind of surprised it doesn't exist (or if it does, I haven't seen it). "Following" certain authors on Kindle doesn't seem to have done anything useful, either.
You can have Goodreads do something like this, in the newsletters and other mail section you can check the 'send me the monthly new releases email', 'only send this to me if it includes an author I've read', and click the customize button and deselect all of the genres.
And then you end up with an email which has new releases by authors you've read before.
I generally have no use for most of what Goodreads does, but this combined with the ability to pull my Kindle purchases in automatically is pretty useful.
